About the role

Key responsibilities & impact

Execute end-to-end network and PLC integration of Laminar’s edge devices into customer OT environments — both onsite and remotely.
Configure and troubleshoot industrial communication protocols including Ethernet/IP, Modbus TCP/RTU, and PROFINET.
Diagnose and resolve network issues in the field: invalid IP configurations, DNS resolution failures, NTP sync problems, and general IT/OT network outages.
Work alongside customer process, IT, and OT teams during deployment pilots.
Contribute to productizing the integration process — identify what is manual and repetitive today and help engineer it away.
Support Site Acceptance Test (SAT) completion and customer sign-off in coordination with the broader FDE team.

What you’ll need

Bachelor’s degree in computer science, Computer Engineering, or Electrical Engineering.

Practical proficiency with Git/GitHub, Python scripting, and Linux command-line fundamentals.
Undergraduate coursework or equivalent demonstrated knowledge in networking fundamentals: IP addressing, subnetting, VLANs, DNS, NTP, and TCP/IP stack.
Comfortable getting hands dirty to debug data-flow problems — you understand what a network trace tells you and you know how to follow a packet.
Portfolio of projects (academic, personal, or professional) demonstrating proficiency in networking, systems integration, debugging, or problem-solving.
Strong cross-functional communicator — able to work across customer IT teams, plant-floor OT engineers, and internal software developers.
